Built-in IP68 magnetic switch to cycle light between high/low/strobe (6Hz)/off. A key feature of the Kevin Jr. is that when installed in an inaccessible location (high on a sailboat mast for example), any remotely installed switch will automatically produce a high beam independent of the built-in switch.
600+ lumen rated high-power LEDs provide the highest lumen-per-watt light, outperforming other LED lights in its class.
